What this shows WK's Innovation Score is 29.9/100 (32nd percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for WK?

Each dot is one of WK’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). WK’s own 11.9 claims/patent is ABOVE the 11.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where WK's grants concentrate

WK Holdings Inc. is a focused PatentsView assignee: 12 CPC subclasses with 42.9% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2020. By volume, WK sits between Wire Master Industry Co., Ltd. and World Award Academy, World Award Foundation, Amobilepay, Inc..

WK's three-year grant acceleration

WK Holdings Inc. shows 1 grants in 2022–2024 against only 2 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
